15 Claims.

The object of the present invention is to provide an adapter orconnector which may be connected directly to the suction nozzle itselfof 1y attached or removed. I A further object is to provide a hoseconnecter which is especially adapted for use upon a welln the cleaner,and which may be easily and quickknown type of cleaner having a suctionnozzle with inlet openings or ports for supplying air to the fabricbeing cleaned adjacent the inlet or suction mouth of the nozzle, asshown and de-,

scribed in the pending application; for l etters Patent filed by GeorgeW. Allenwand Lena, B. Allen on August 27, 1929, SerialNo. 388,729,.

With these objects in view the present inven; tion consists in thedevices and combinations of devices hereinafter described and moreparticularly defined in the claims.

In the accompanying drawings which illustrate what is now considered thepreferred form of the present invention as embodiedin-a hose connecteradapted for use on thesuction nozzle shown and described in saidapplication, Fig. 1 is a side elevation of a cleaner with the adapterattached thereto; Fig. 2 is a top plan View on an enlarged scale of thefront portion thereof; Fig. 3 is a transverse vertical sectional viewonr line 33 of Fig. 2; Figs. 4 and 5 are longitudinal, vertical sectionalviews on lines 4-4 and 5%5respectively of Fig. 2; and Fig. 6 isaperspective view of the hose connecter detached.

' The cleaner illustrated in Fig. 1 comprises the usual fan casing 6,with the forward and downward extension .7, flaring laterally into thenozzle '8. An electric motor 9 is mounted on the top of the casing, andthe rear end of the machine is supported by the wheels 10. The dust bag11 and propelling handle 12 are shown only in part. u I w The nozzle, asshown in said Allen application and as illustrated in Figs. 4 and 5 ofthe present drawings, comprises the inletslot or mouth 14 extendingacross substantially the entire width of the nozzle and communicatingwiththe interior of the fan casing 6 through the usual dust or passagewithin the part '7. Adjacent the nozzle; mouth at the front and rear arethe air ports or openings 16 through which air: is detains the apparatusin upright position.

livered from the inlet ports 17 onto the surface of the fabric beingcleaned to loosen any: threads or dirt upon or in the fabric and tocarry the same into the suction mouth. An' endless rubber bumper band 18is held in the recess of '60 groove 19in the front, rear, and end wallsof the nozzle. i

In normal operation the front end of the cleaner is supported by theflat bottom faces 18 which form part of. the nozzle structure, all asshown and described in said Allen application. The adapter or hoseconnector which forms the subject of the presentinvention is adapted notonly to coverand close the suction .or inlet mouth of the nozzle, but"also to cut off the air ports or openings at the" front and rearthereofu In addition it is provided with means for quickly and securelyclamping on the nozzle where it supports the front end of the cleanerand main- 7 5 As shown in Fig. 6, 'the;adapter or connecter comprises atrough-shaped body portion having substantially vertical sidewalls22'and a bottom consisting of the fiat end'portions 24 and'adeepormiddle or intermediate portion 26. This intermediate portion has its,bottom inclined inwardly' from each 'end, as at 27, and curveddownwardly and forwardly from the rear, as at 28. .At the bottom of thefront Wallis' the tubu-k lar extension'or fitting 29 to receive thesuction hose 30, as shown in Fig. 1. 7

At each end oftheadapter is a small air opening 31 in the vertical wallfor the purpose of admitting a current of air which will prevent thelodgment and deposit of dust ordirtat the ends of the-adapter. I i

The adapter i is provided near each end with supports or legs 32-whichconsists of U-shaped members having a stiffening rib or lip 34 at eachedge, the upperends of the vertical members being connected as by spotweldingto the front and rear walls. The height of these' legs is suchthat the adapter and front-end of the cleaner are supported solely bythese logs, the lower middle portion 26 being above and out of contactwith the floor or other surface; Owing to the wide 1 spacing apart ofthese legs on the adapter, the

cleaner is maintained securely in erect position without danger of beingtipped over even when it .105

is drawn about by thehose. These supporting legs are of such a width andtheir front and rear bottom corners are Soroundedthat little resistanceis offered to the movement of the cleaner and the latter may be drawnabout by the hose with a minimum of efiort, even over deep pile fabric.

The converter is connected or attached to the nozzle by means of thespring clips 36 pivoted at their rear, ends to the top of the rearvertical members'of the supporting legs. These members are formed withtwo extensions or lugs at their tops spaced from one another and rolledover to provide the cylindrical supports 40 for the pivot pin 42. I

The free ends of the clips are formed with a rounded catch or shoulder44 to engage'beneath the bead or out-turned lip 45 on the top edge ofthe vertical walls or the adapter. An extension or thumb piece asfacilitates the engagement and disengagement of the catch or shoulderand the lip when it is desired to attach or remove the adapter. Thehorizontal or body portion of the clip is struck downwardly to form therounded rib 48 to engage the top of the nozzle, as shown in Fig. 5, whenthe clip is in operative position, thus holding the adaptertightly onthenozzle by the spring of the clips. 7 V a In normal operation of thecleaner, that is, when it is being propelled over a rug to clean thesame, the adapter or hose connection is not attached andthe nozzle restsdirectly upon the rug. When however, it is desired to use the '3flexible hosewith the hand tool, the front end or" the cleaner isslightly raised, the adapter with the connected hose already attached ispositioned beneath the nozzle, which is then lowered into I place inthe. trough-shapedbody 0f the adapter,

the spring clips are turned over the top of the ,nozzle and forced intooperative position beholds the connecter and nozzle in close yieldingengagement, with the rubber bumper band 118 compressed between thenozzle :and the walls of the converter to prevent any leakage of airdownwardly therebetween. 1 By reason of the fiat bottom end portions 24,which when the converter is in position on the nozzle are inv closeproximity tothe bottom of the nozzle, and of the. lower middle portion25,

the cross sectional area of the air duct or passage through theconverter is restricted and the formation of pocketsor dead spaces'isavoided, thus preventing reduction of air velocity and the resultingdeposit of dust and dirt. w

' The converter, of hose connecter herein shown and described mayconveniently be stamped from sheet material with corresponding light Itis self-contained, that is, it has no loose or separate parts to bemislaid or lost, and requires no movable or disconnectible parts on thecleaner.

Whilethe adapter herein shown and described is especially designed foruse with the nozzle of said Allen application, it is obvious thatit maybe used with other types of nozzles, and may be embodied in other formsand arrangements within the scope ofthe appended claims.
